  • What is the mechanism of C-H activation, and does the Cu monomer versus Cu dimer site promote a different reaction mechanism?

  • What is the influence of the ligands in the first coordination sphere on oxidant activation and ultimately reactivity?

  • To what exent is catalyst activity, specificity and selctivity influenced by the second coordination sphere and confinement effects?

Open questions
  • What is the rate-limiting step in LPMO catalysis and what is the nature of the catalytic Cu-oxygen species?

  • What are the functional implications of the huge variation among LPMO sequences and how does this variation affect copper reativity?

  • What is the relative importance and O2 and H2O2 as co-substrate and how does the nature of the co-substrate affect the catalytic mechanism and its intermediates?

  • What factors determine substrate specificity?

  • What is the role of confinement in LPMO performance?

  • How can autocatalytic oxidative damage to the LPMO active site be prevented?

  • Can we, by looking into nature and, more so, by clever design, expand the substrate range of LPMOs to include alkanes or other polymers such as plastics?
Open questions
  • What is the effect of the redox/coordinative environment on the formation of (multimeric) active sites?

  • What is the role of framework protons on the reaction?

  • What is the role of water on the reaction?

  • What is the rate-determining step? Is it the same for all materials?

  • How much of the Cu is available for active site formation? How does this vary in different zeolites?

  • Can structure-activity relationships be described by simple parameters?
